DESPITE meeting her future boyfriend while filming The Rum Diaries in 2011 Amber Heard admits that dating Johnny Depp is difficult because of hectic work schedules.

The 27-year-old American actress has been in a relationship with Johnny, 50, for a year and explains that she has had to adjust to the fame that comes with her job and going out with a Hollywood superstar.

It is really hard when you spend your life living out of a suitcase

"It is really hard when you spend your life living out of a suitcase," says Amber. "But it really does weed out superficial people - if someone is still with you after the second movie then they are probably a good one. I like to trust people in general - it is the Southern girl in me."

Amber and Johnny, who split from his partner of 15 years Vanessa Paradis in June last year, are filming together again in the movie London Fields, due for release next year.

Amber tells the December issue of Company magazine, out November 13, that she believes film roles for women are better over here. "I think in Europe things are better but in the US we still have characters who are defined by physical attractiveness."
